An organic ion in which a carbon atom carries a negative charge is known as a carbanion. An organic ion in which a carbon atom carries a positive charge is known as a carbocation. The reaction of NaOH(aq) with 1-bromobutane takes place via an $\text{S}_\text{N}2$ mechanism. What is the first stage in the mechanism?
- Aattack by a nucleophile on a carbon atom with a partial positive charge
- Bheterolytic bond fission followed by attack by an electrophile on a carbanion
- Cheterolytic bond fission followed by attack by a nucleophile on a carbocation
- Dhomolytic bond fission followed by attack by a nucleophile on a carbocation
