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 ?

Text Solution

Verified by Experts

The correct Answer is:

b) Z has seven, electrons in its valence shell. It is the most electronegative element. Therefore, HZ will have the highest dipole moment.
