Question

Predict the type chemical bond present in given compounds (Electro negativity of Na=0.9 ,Cl=3.9 ,H=2.1, O=3.5 ) NaCl ,HCl ,H2O ,NaH

Answer 1

Answer:

NaCl - ionic bond

HCl - ionic bond

H2O - covalent bond

NaH - ionic bond

Explanation:

an electronegativity differences of 1.7 or more leads to ionic bond.and if less then covalent bonding.this is a general rule.
