Final answer:
The organic product in the reaction between ethanol and pent-1-ol is ethyl pentanol (c)
Step-by-step explanation:
The organic product in the reaction between ethanol and pent-1-ol is ethyl pentanol (c). Ethyl pentanol is formed by the substitution of a hydroxyl group (OH) of ethanol with a pentyl group (C5H11) from pent-1-ol. This substitution reaction results in the formation of a longer alkyl chain.
