Mock Test 1 — Chemical Bonding and Molecular Structure

Type of bonding in NaCl:

Hybridization of S in SF₆:

Maximum number of $sp^2$ hybrid orbitals on the central atom:

Geometry of SF₄:

Bond order of $N_2^+$:

Number of $\pi$ bonds in C₂H₂:

Most polar bond:

The molecule that does NOT have dipole moment:

Ice floats on water because:

Hybridization of central atom in [PtCl₄]²⁻:

Number of lone pairs in central atom of XeF₂:

Bond order of CO molecule:

Number of $\sigma$ bonds in benzene (C₆H₆):

Assertion (A): BeCl₂ is linear with $sp$ hybridization. Reason (R): Be has only 2 valence electrons; both undergo sp hybridization with chlorines.

Assertion (A): Boiling point of HF is higher than HCl. Reason (R): HF forms intermolecular hydrogen bonds while HCl does not.
