Question 5 (1 point)

For the shown compound, what are the molecular geometries in the left region (carbons in benzene ring), center region (single bonded carbon), and right region (carbon and nitrogen in triple bond), respectively?

Question 5 options:

tetrahedral, bent, trigonal planar

trigonal planar, tetrahedral, linear

trigonal pyramidal, trigonal pyramidal, trigonal planar

trigonal planar, trigonal pyramidal, linear

tetrahedral, linear, linear

tetrahedral, bent, trigonal planar

trigonal planar, tetrahedral, linear

trigonal pyramidal, trigonal pyramidal, trigonal planar

trigonal planar, trigonal pyramidal, linear

tetrahedral, linear, linear

Explanation / Answer

The carbons in benzene ring are all sp2 hybridised. So they are all trigonal planar.

The carbon in the middle (single bonded carbon) is sp3 hybridised and geometry is tetrahedral.

The carbon in triple bond with nitrogen is sp hybridised and it is linear.

The correct option is: trigonal planar; tetrahedral; linear
