and

CC{l_4}

, the covalent bond character varies as

View answer and explanation

Correct option: C

LiCl < BeC{l_2} < BC{l_3} < CC{l_4}

The correct answer is C (

LiCl < BeCl_2 < BCl_3 < CCl_4

) because covalent character increases with the polarizing power of the cation, which increases with decreasing size and increasing charge.
