Write Either A or B A. Explain VSEPR Theory with an example (H2O or NH3) to predict the shapes of these molecules? How do electron geometry and Molecular geometry differ?

B. Write a short note on Valence Bond Theory. How sigma and pi bonds formed?

The boiling point of propanoic acid is higher than that of 1-butanol because: propanoic acid has a higher molecular weight than 1-butanol. propanoic acid is more soluble in water than 1-butanol. propanoic acid is a better hydrogen bond donor than 1-butanol. propanoic acid forms hydrogen bonded dimers and 1-butanol does not. 1-butanol forms hydrogen bonded dimers and propanoic acid does not.
