Question

The element oxygen would be expected to form covalent bond(s) in order to obey the octet rule.use the octet rule to predict the formula of the compound that would form between oxygen and hydrogen , if the molecule contains only one oxygen atom and only single bonds are formed.formula:

Answer 1

Oxygen atom has 6 valent electrons, 2 of them unpaired.
