- A-II, B-I, C-III, D-IV
- A-II, B-I, C-IV, D-III
- A-IV, B-III, C-II, D-I
The Correct Option is C
Approach Solution - 1
Correct answer is (C): A-II, B-I, C-IV, D-III
Approach Solution -2
- A. \( \text{XeF}_4 \) has a square planar structure.
- B. \( \text{SF}_4 \) has a see-saw shape.
- C. \( \text{NH}_4^+ \) has a tetrahedral geometry.
- D. \( \text{BrF}_3 \) has a bent T-shaped structure.
A-I, B-I, C-IV, D-III.
In this matching, the structures of various molecules are being analyzed based on the number of bonding pairs and lone pairs. The tetrahedral geometry of \( \text{NH}_4^+ \) is typical for molecules with four bonding pairs and no lone pairs. \( \text{BrF}_3 \), with its lone pairs, adopts a bent T-shaped structure, while \( \text{XeF}_4 \) adopts a square planar structure due to the presence of two lone pairs and four bonding pairs.

Questions Asked in JEE Main exam
A bob of mass \(m\) is suspended at a point \(O\) by a light string of length \(l\) and left to perform vertical motion (circular) as shown in the figure. Initially, by applying horizontal velocity \(v_0\) at the point ‘A’, the string becomes slack when the bob reaches at the point ‘D’. The ratio of the kinetic energy of the bob at the points B and C is:

P-Block Elements
- P block elements are those in which the last electron enters any of the three p-orbitals of their respective shells. Since a p-subshell has three degenerate p-orbitals each of which can accommodate two electrons, therefore in all there are six groups of p-block elements.
- P block elements are shiny and usually a good conductor of electricity and heat as they have a tendency to lose an electron. You will find some amazing properties of elements in a P-block element like gallium. It’s a metal that can melt in the palm of your hand. Silicon is also one of the most important metalloids of the p-block group as it is an important component of glass.
P block elements consist of:
- Group 13 Elements: Boron family
- Group 14 Elements: Carbon family
- Group 15 Elements: Nitrogen family
- Group 16 Elements: Oxygen family
- Group 17 Elements: Fluorine family
- Group 18 Elements: Neon family
