After the successful completion of examination, the tentative answer keys has been released by the coaching institutions. The official answer key also has been released by the NTA on **13th January 2020** for January session JEE Main exam & in the month of April 2020 for April session exam. The answer key is a set of answers for the questions that will be asked in the exam.

The answer key help the students in evaluating the right answers of the question and also helps in calculating their expected score. Starting from the exam date till the result date, a highly pressure and tensed time is very hard to pass by students without knowing that how they have performed on exam sheet. But by evaluating answer key they can lower down their tension.

**Paper:1**

**Shift 1 (Chemistry):**

**Q.1)** Among the following statements that which was not proposed by Dalton was:

(a) Matter consists of invisible atoms

(b) When gases combine or reproduced in a chemical reaction they do so in a simple ratio by volume provided all gases are at the same T and P.

(c) Chemical reactions involve the reorganization of atoms. These are neither created nor destroyed in a chemical reaction

**Answer:** Option (b) is correct as it was proposed by Gay Lussac’s law of gaseous volume.

Therefore, Option(b) is correct.

**Q.2)** Which theory explains completely about bonding in coordination compounds?

**Answer: **Valence bond theory

**Q.3)** Which among following is the purest form of iron:

- Cast iron
- Wrought iron
- Pig iron
- None of these

**Answer:** Option II. Wrought iron

**Q.4)** The atomic radius of Ag is closest to:

(a) Ni

(b) Cu

(c) Au

(d) Hg

**Answer: **The atomic radius of Ag is closest to Hg.

Therefore, **Option (d) is correct.**

**Q.5) **The relative strength of interionic/intermolecular forces in decreasing order is:

(a) Ion-dipole > dipole-dipole > Ion-ion

(b) dipole-dipole > ion-dipole > ion-ion

(c) ion-ion > ion-dipole > dipole-dipole

(d) ion-dipole > ion-ion > dipole-dipole

**Answer: **The correct order of intermolecular forces is:

Ion-ion > ion-dipole > dipole-dipole

Therefore, **Option(c) is correct.**

**Q.6)** The increasing order of pKb for the following compounds will be:

(a) NH2-CH=NH

(b) Image

(c) CH3NHCH3

**Answer:**

**Thus, the increasing order of basicity is: **

(a) > (b) > (c)

**Q.7)** Match the following:

(i) Riboflavin (a) Beriberi

(ii) Thiamine (b) Scurvy

(iii) Pyridoxine (c) Cheilosis

(iv) Ascorbic acid (d) Convulsions

**Answer:**

** **(i) Riboflavin – (c) Cheilosis

(ii) Thiamine – (a) Beriberi

(iii) Pyridoxine – (d) Convulsions

(iv) Ascorbic acid – (b) Scurvy

**Q.8) **The oxidation number of potassium in K_{2}O , K_{2}O_{2} and KO2, respectively is :

**Answer:**

**For K _{2}O:** 2x – 2 = 0

x = 1

**For K _{2}O_{2}: **2x – 4 = 0

x = 2

**For KO _{2}: **x – 4 = 0

x = 4

**Q.9)** The number of orbitals associated with quantum numbers n = 5, m_{s} = +1/2 is:

**Answer:**

We have:

n – 5, m_{s} = +1/2

Thus, values of l are from 0 to (n-1)

l = 0 to 4

Thus, values of l are 5s, 5p, 5d, 5f and 5g

Now, the total number of orbitals = n^{2} = 5^{2} = 25

**Q.10)** At 35^{o}C, the vapour pressure of CS_{2} is 512mm Hg and that of acetone is 344mm Hg. A solution of CS_{2} in acetone has a total vapour pressure of 600mm Hg. The false statement among the following is:

(a) CS_{2} and acetone are less attracted to each other than to themselves.

(b) Heat must be absorbed in order to produce the solution at 35^{o}C.

(c) Raoult’s law is not obeyed by this system.

(d) A mixture of 100ml CS_{2} and 100ml acetone has a volume of <200ml.

**Answer:**

We have:

P_{observed} = 600Hg

We know:

P_{calc} = P^{o}_{A}x_{A} + P^{o}_{B}x_{B}

= 512x + 344 – 344x

= 168x + 344

= 512 ( if x =1 for miximum value)

Thus, P_{calc} < P_{observed}

Thus, the process is deviated from Raoult’s law, showing positive deviation from Raoult’s law.

\: 0}” v:shapes=”Picture_x0020_12″>, i.e, heat absorbed

Therefore, **Option(d) is correct.**

**Q.11) **In comparison to the zeolite process for the removal of permanent hardness, the synthetic resins method is:

(a) Less efficient as it exchanges only anions

(b) More efficient as it can exchange only cations.

(c) Less efficient as the resins cannot be generated

(d) More efficient as it can exchange both cations and anions

**Answer:**

The synthetic resins method is more efficient as it can exchange both cations and anions.

Therefore, **Option(d) is correct.**

**Mathematics:**

**Q.1)** If the variance of first n natural number is 10 & variance of first m even natural number is 16, then the value of m+n is:

**Answer:** 18

**Q.2)** If 49^{k }+1 is a factor of 49^{125 }+ 49^{124}+…..49+1, then find K

**Answer:** 63

**Q.4)** How many six-digit numbers can be formed using digit 1, 3, 5, 7, 9 such that in each number each digit should be used at least once.

**Answer:** 1800

**Q.5)** Sum of 5 no. in AP is 25 & their product is 2520, if one of them is -1/2 then finds the largest number?

**Answer:** 16

**Q.6)** If linear equation,

2x + 2ay + az= 0

2x + 3by + bz= 0

2x + 4cy + cz= 0

where a, b, c R are non-zero & are distinct, has non-zero solutions then

- 1/a, 1/b, 1/c are in A.P
- a, b, c in AP
- a, b, c are in CP
- a+b+c= 0

**Answer:** Option 1

**Q.7)** The total no. of 6 digit number that can be formed using all the digits 1, 3, 5, 7, 9 only is?

**Answer:** 1800

It seems that the computer based examination of JEE Mains conducted on 8th Apr 2017 is easier compared to the pen and paper based exam conducted on Apr 2nd. In that case, the students who opted for pen and paper based exam on 2nd April are at a disadvantage, both in terms of time (one less week for preparation) and increased difficulty. Would CBSE do any moderation between both pen and paper and computer based tests to bring students onto the same ground ?

When will the solutions for online exam on8 April be available ??
