. (a) BeF2 (b) BCl3
(c) NH3
(d) CIF3​

Answer 1

Answer:

bc13

Explanation:

Answer 2

Answer:

(b) BCl3

Explanation:

Short trick :

Add their valence electrons

then divide the sum with

1. 2 (If 2 < sum ≤8)
2. 8 (If 8< sum ≤56)
3. 18 (If 56< sum )

{Take reference from attachment }

Add all the quotients and subtract the surrounding atoms to get no. of lone pairs

Note : I mistakenly written BeF2 linear it's not linear it's sp3 hybridised and shape is similar to H2O.
