# Organic Chemistry Divergent-Convergent reaction of 2-butanol

Chemistry Level 2

A solution of $$\text{2-butanol}$$ was split into two flasks labeled $$A$$ and $$B$$. A mixture of $$\text{phosphorus}$$ and $$\text{bromine}$$ was added to flask $$A$$; to flask $$B$$ aqueous $$\text{hydroxide}$$ was poured in. The contents of flask $$B$$ were then transferred to flask $$A$$. A product resulted from the mixture.

Input your answer as the number of $$\text{hydrogen}$$ divided by the number of $$\text{carbons}$$ in the final product, to two decimal places: $\text{Answer }= \frac{\text{Number of Hydrogens}_{\text{ product}}}{\text{Number of Carbons}_{\text{ product}}}.$

Hint: The reaction is $$S_N2$$, not $$E2$$.
