Question

In which of the following there exists a p $\pi$ - d $\pi$ bonding?

• A. Diamond
• B. Graphite
• C. Dimethylamine
• D. Trisilylamine.

Answer 1

Answer: (D)

Trisilylamine, $N(Si{H}_3{)}_3$ has a planar structure where N is $s{p}^2$-hybridized and there is a $\pi$-$\pi$ overlapping (side wise) due to the filled unhybridized p-orbital of N and empty d- orbitals of Si atoms.
