Answer 1

this is the answer of your first two questions

Answer 2

⚡⚡Here is your answer⚡⚡

(a)H-F>H-CL>H-Br>H-I

Due to decrease in electron gravity difference , u decrease.

(b)CH3-CL>CH3-F>CH3-Br>CH3-I

The bond length of C-Cl>C-F

So the u of CH3 -Cl>CH3-F

(c)NH3>NF3>BF3

(d)H2S>NH3>H2O>HF

(e)CH3CL>CH2CL2>CHCL3>CCI4

Due to increase in bond angle 'u' decrease
