provide a specific step by step mechanism ( with curved arrow notation) for the conversion of 4-hydroxybutanal to 4-chloro-1-butanol, and then from 4-chloro-1-butanol to tetrahydrofuran. Show all reasonable steps that led to major substrate product(s).use of a protecting group should occur at least once during the course of the mechanism.
