Number of

P\mathrm{ }--\mathrm{ }O

bonds in

{\mathrm{P}_4}{\mathrm{O}_{10}}

View answer and explanation

Correct option: B

16

Option B (16) is correct because in the structure of

P_4O_{10}

, each phosphorus atom is bonded to four oxygen atoms, resulting in a total of 16 P-O bonds.

When two atomic orbitals combine, they form:

View answer and explanation

Correct option: B

Two molecular orbitals

Option B (Two molecular orbitals) is correct because the combination of two atomic orbitals always results in the formation of two molecular orbitals (one bonding and one antibonding).

In which of the following molecules,

{\sigma _{2{p_z}}}

molecular orbital is filled after

{\pi _{2{p_x}}}

and

{\pi _{2{p_y}}}

molecular orbitals

View answer and explanation

Correct option: C

{N_2}

Option C (

{N_2}

) is correct because in

N_2

, due to less intermixing, the

{\sigma _{2{p_z}}}

molecular orbital is filled after

{\pi _{2{p_x}}}

and

{\pi _{2{p_y}}}

molecular orbitals.

124 Easy

Understanding +4 | -1

Strongest hydrogen bond is shown by

View answer and explanation

Correct option: C

Hydrogen fluoride

Option C is correct because Hydrogen Fluoride (HF) exhibits the strongest hydrogen bonding due to the high electronegativity of Fluorine.
