Do `NH_(3)` and `BF_(3)` have same shape ?

Both NH_(3) and NF_(3) have identical shapes and same state of hybridisation. Both N-H and N-F bonds have almost the same electronegativity difference. But still, the two molecules have different dipole moment values. How will you account for it ?

BF_(3) is.

The tendency of bF_(3), BCl_(3) and BBr_(3) behave as Lewis acid decreases in the sequnece (a) BCl_(3) gt BF_(3) gt BBr_(3) (b) BBr_(3) gt BCl_(3) gt BF_(3) (c) BBr_(3) gt BF_(3) gt BCl_(3) (d) BF_(3) gt BCl_(3) gt BBr_(3)

Which of the following statement is not correct ? (a) [Ni(H_(2)O)_(6)]^(2+) and [Ni(NH_(3))_(6)]^(2+) have same value of CFSE ( b) [Ni(H_(2)O)_(6)]^(2+) and [Ni(NH_(3))_(6)]^(2+) have same value of magnetic moment

NH_(3) and BF_(3) from adduct readily because they from

In the following questions, a statement of assertion (A) is followed by a statement of reason (R ) A: bond angle of BF_(3) and NF_(3) are different. R : Both the molecules are having different shape

(a) BF_(3) and BrF_(3) molecule has different shapes. Expain. (b). C Cl_(4) cannot be hydrolysed but SiCl_(4) can be, why?

He_(2)^(3) and He_(1)^(3) nuclei have the same mass number. Do they have the same binding energy ?
