Question

The bond energy of Si-O bond is ____________

(a) 37 kJ/mol

(b) 115 kJ/mol

(c) 248 kJ/mol

(d) 502 kJ/mol

This question was posed to me during an interview for a job.

Question is from Silicones and Polymeric Composites in portion Polymers of Engineering Chemistry I

Answer 1

Right answer is (d) 502 kJ/mol

Easy explanation: The bond energy of Si-O bond is 502kJ/mol. The bond energy is a measure of the amount of energy needed to break apart one mole of covalently bonded gases and Si-O bond is very strong.
