Q. The $ BCl_{3} $ is a planar molecule whereas $ NCl_{3} $ is pyramidal, because:

Solution:

In boron trichloride, boron is $sp$ hybridised and there is no lone pair on boron while in nitrogen. It is $sp$ hybridised and there is a lone pair of electron in nitrogen. Hence, due to this reason $ BCl_{3} $ is a planer molecule and $ NCl_{3} $ is a pyramidal molecule.
