Which of the following statements is true for carbonyl group?
Options
- ACarbon atom is sp ³ hybridised
- BCarbon atom forms three sigma bonds
- CC - C - O - bond angle is 90^
- DThe carbonyl bond is weaker as compared to double bond in alkene
Correct answer
B. Carbon atom forms three sigma bonds
Step-by-step 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.
