Question
Carbon forms numerous compounds with hydrogen, called hydrocarbons. Which of the following statements is not correct.
A) When carbon is bonded to 4 hydrogen atoms to form CH4, the 2s and the three 2p orbitals undergo hybridization to form four sp3 orbitals.
B) Through hybridization of the carbon atom, a total of four lone electron orbital sites are established. These sites are called p4 orbitals.
C) Making four bonds lowers the potential energy for the system.
D) The observed geometry for the methane molecule is tetrahedral. Each bond angle is exactly 109.5°.
Explanation / Answer
B) Through hybridization of the carbon atom, a total of four lone electron orbital sites are established. These sites are called p4 orbitals.
Because through hybridization of the carbon atom the 2s and the three 2p orbitals of C atom undergo hybridization to form four sp3 orbitals.
