The BCl3 is a planar molecule whereas NCl3 is pyramidal because [1995]...
As there is no lone pair on boron in BCl3 therefore no repulsion takes place. But there is a lone pair on nitrogen in NCl3. Therefore repulsion takes place. Thus BCl3 is planar molecule but NCl3 is a pyramidal molecule.

BCl3 have sp2 hybridisation and no lone pair of electron on central atom but NCl3
have sp3 hybridisation and also contains one lone pair of electron on nitrogen, so BCl3 is planar.
have sp3 hybridisation and also contains one lone pair of electron on nitrogen, so BCl3 is planar.

The BCl3 is a planar molecule whereas NCl3 is pyramidal because [1995]...
BCl3 is a planar molecule whereas NCl3 is pyramidal because BCl3 has no lone pair but NCl3 has a lone pair of electrons.
Explanation:
Molecular geometry is determined by the arrangement of atoms and lone pairs of electrons around the central atom. The presence of lone pairs of electrons can affect the shape of a molecule.
BCl3:
In BCl3, boron (B) is the central atom surrounded by three chlorine (Cl) atoms. Boron has an electronic configuration of 1s2 2s2 2p1, which means it has three valence electrons. Each chlorine atom contributes one electron to form a covalent bond with boron, resulting in three B-Cl bonds.
The Lewis structure of BCl3 shows that there are no lone pairs of electrons on the central boron atom. This arrangement of atoms and electrons results in a trigonal planar geometry. The three chlorine atoms are arranged in a flat plane around the boron atom, with bond angles of 120 degrees.
NCl3:
In NCl3, nitrogen (N) is the central atom surrounded by three chlorine (Cl) atoms. Nitrogen has an electronic configuration of 1s2 2s2 2p3, which means it has five valence electrons. Each chlorine atom contributes one electron to form a covalent bond with nitrogen, resulting in three N-Cl bonds.
The Lewis structure of NCl3 shows that there is one lone pair of electrons on the central nitrogen atom. This arrangement of atoms and electrons results in a pyramidal geometry. The three chlorine atoms are arranged in a triangular base, with the nitrogen atom at the apex of the pyramid. The bond angles are slightly less than 109.5 degrees due to the repulsion between the lone pair and the bonding pairs.
Conclusion:
The presence of a lone pair of electrons on the central nitrogen atom in NCl3 causes the molecule to have a pyramidal shape. In contrast, the absence of a lone pair on the central boron atom in BCl3 allows the molecule to have a planar shape. Therefore, the correct answer is option D - BCl3 has no lone pair but NCl3 has a lone pair of electrons.
