JEE Main 2023 Chemistry Questions with Solutions

Section – A

Question 1:

Which of the following are the Green house gases ?
(A) Water vapour
(B) Ozone
(C) I₂
(D) Molecular hydrogen

Choose the most appropriate answer from the options given below :

\(HS-CN \xrightarrow{} HO-C = NH CN \)

(1) (A)
(2) (B)
(3) (C)

Question 3:

In the wet tests for detection of various cations by precipitation, Ba\(^{2+}\) cations are detected by obtaining precipitate of :

(1) Ba(OAc)\(_2\)
(2) BaCO\(_3\)
(3) BaSO\(_4\)
(4) Ba(ox) : Barium oxalate

Correct Answer:(2) BaCO\(_3\)

View Solution

In wet testing, \((NH_4)_2CO_3\) is used as a group reagent for detecting 5th group cations such as \( Ba^{2+}, Ca^{2+}, Sr^{2+} \). The precipitation of barium carbonate, BaCO\(_3\), is used to confirm the presence of \( Ba^{2+} \).
The reaction is: \[ Ba^{2+} + (NH_4)_2CO_3 \rightarrow BaCO_3 \downarrow + NH_4^+ \] Quick Tip: Barium carbonate forms a white precipitate when \( Ba^{2+} \) reacts with \( (NH_4)_2CO_3 \) in water.

Question 21:

If the formula of Borax is Na\(_2\)B\(_4\)O\(_7\).(OH)\(_2\), then x + y + z = ?

The formula of borax is Na\(_2\)B\(_4\)O\(_7\).(OH)\(_2\)

View Solution

Borax has the following formula: Na\(_2\)B\(_4\)O\(_7\).(OH)\(_2\)
This formula contains:
- 2 sodium atoms (Na)
- 4 boron atoms (B)
- 7 oxygen atoms (O)
- 2 hydroxyl groups (OH).
Thus, adding these values gives: \[ 2 + 4 + 7 + 2 = 17 \]
Therefore, \( x + y + z = 17 \). Quick Tip: Ensure you correctly count all atoms and functional groups in molecular formulas for accurate results.

Question 30:

See the following chemical reaction: \[ Cr_2O_7^{2-} + XH^+ + 6Fe^{2+} \rightarrow YCr^{3+} + 6Fe^{3+} + ZH_2O \]
The sum of \( X \), \( Y \) and \( Z \) is ___ .

Correct Answer: 23

View Solution

First, balance the chemical equation: \[ Cr_2O_7^{2-} + 14H^+ + 6Fe^{2+} \rightarrow 2Cr^{3+} + 6Fe^{3+} + 7H_2O \]
From the balanced equation, we can identify the coefficients: \[ X = 14, \quad Y = 2, \quad Z = 7 \]
The sum of \( X \), \( Y \), and \( Z \) is: \[ X + Y + Z = 14 + 2 + 7 = 23 \] Quick Tip: When balancing redox reactions, first balance the elements other than oxygen and hydrogen, then balance oxygen by adding water molecules, and finally balance hydrogen by adding H+ ions. Then, balance the charges by adding electrons.
