Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

Lone Pair availability on Nitrogen decreases as it undergoes backbonding....so less basic

got this shristy??
![eduncle-logo-app]()
means due to presence of vacant orbital of Si it is planer
![eduncle-logo-app]()
so here first basic...as less availability of lone pair so less basic

option B
Nitrogen (N) atom in trimethylamine [N(CH3)3] is sp3 hybridised and non bonding electron pair of N is localised. Therefore it is more basic. On the other hand N atom of trisilylamine [N(SiH3)3] is sp2 hybridised. This is due to the participatlon of non-bondlng pair of N into pπ-dπ back banding. Due to this delocalization of non-bonding electron pair of N in trisilylamine it is less basic.
