**Question 3****Problem Statement:**Predict the major product and a mechanism for the following reaction:**Chemical Reaction:**- Reactants: A cyclohexyl group attached to a propynyl group (alkyne).- Reagents: Excess hydrochloric acid (HCl).**Explanation:**The given compound is an alkyne attached to a cyclohexyl ring. In the presence of excess HCl, hydrohalogenation occurs. This reaction typically proceeds via a Markovnikov addition, where the hydrogen atom adds to the carbon with the most hydrogen atoms (the terminal carbon of the alkyne), leading to the formation of a dichlorinated alkane.**Mechanism:**1. **First Addition of HCl:** - The alkyne reacts with HCl, where the hydrogen ion (H⁺) adds to the terminal carbon, and the chloride ion (Cl⁻) adds to the more substituted carbon. This forms a vinyl chloride.2. **Second Addition of HCl:** - The formed vinyl chloride reacts with another equivalent of HCl. - The hydrogen adds to the carbon with the Cl from the first addition, and another chloride ion adds to the neighboring carbon, forming a geminal dichloride.**Major Product:**The major product is a geminal dichloride, where both chlorine atoms are added to the carbons of what was initially an alkyne.

There are many mechanisms in organic chemistry such as nucleophilic substitution, nucleophilic addition, elimination reaction, electrophilic substitution, etc. Elimination reactions involve elimination of any group. The dehydration of alcohol is also an example of elimination.The following reaction is an addition reaction in which alkyne attack on the hydrogen atom of the HBr and release chloride ion followed by the formation of carbocation. Then, addition of bromide ion takes place. And the whole mechanism will repeat again. The reaction is given as: The mechanism is given as:
