Elements X,Y and Z have 4,5 and 7 valence electrons respectively, (i) Write the molecular formula of the compounds formed by these elements individually with hydrogen (ii) which of these compounds will have the highest dipolw moment ?

Explanation

`Hunderset(H)overset(H)(underset(* * )overset(* * )(":X"":"))H" "Hunderset(H" "H)overset(H)(underset(* *)overset(* *)(":"Y":"))H" "underset(* *)overset(* *)(":"Z":")H`
The compound Z- H has maximum dipole moment value since it is linear.
