Question

Answer the given statements as True (T) or false (F).

1. The orbitals which have equivalent energy can take part in hybridisation.
2. The number of hybrid orbitals is equal to the number of atomic orbitals mixed.
3. Hybridisation is a hypothetical concept which includes the mixing of electrons.
4. A hybrid orbital only forms $\sigma$ bond.

• A. TTTT
• B. TTFF
• C. TTFT
• D. TTTF

Answer 1

The correct option is C TTFT

Hybridisation is a hypothetical concept which comprises of mixing of atomic orbitals with similar energy not electrons.

The number of hybrid orbitals is always equal to the number of mixed atomic orbitals.

The hybrid orbitals are equivalent in shape and energy which favours the maximum overlap of orbitals and gives rise to $\sigma$ bonds only.
