Question

Mention true (T) or false (F) for the following set of statements.
i) There is a sharing of electrons between two atoms in a covalent bond.
ii) The covalent bond could be polar or non polar.
iii) In a covalent bond there is no complete transfer of electrons.
iv) Covalent molecules have bonds that do not have directional nature.

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

Answer 1

The correct option is D TTTF

a) Covalent bond is formed by sharing of electrons according to Lewis theory.
b) It could be polar like in water $H_{2}O$ or non polar like in $C{l}_2$.
c) It is just sharing and hence no transfer of electrons.
d) Covalent bonds are directional, since they involve overlap of orbitals that have definite orientation.
