Which of the following statements is true for carbonyl group?

Which of the following statements is true for carbonyl group?
  1. Carbon atom is $\mathrm{sp}^{3}$ hybridised
  2. Carbon atom forms three sigma bonds
  3. $\mathrm{C}$ - $\mathrm{C}-\mathrm{O}$ - bond angle is $90^{\circ}$
  4. The carbonyl bond is weaker as compared to double bond in alkene

Solution

In carbonyl group- C atom is sp2 hybridised and forms three sigma bonds. The CCO bond angle is 120 degress and CO bond is stronger than of alkene bacuse oxygen has higher electronegativity than carbon which results in partial ionic character in CO bond which makes it stronger.
