Question 11
On adding first reagent, here it acts as a base hence it will abstract a proton or hydrogen from the reactant to form a carbanion which will then react with second reagent to give an alkyne which then react with third reagent to give a ketone as the final product.
Question 14
Alkyl groups, hydroxyl groups and amide groups are activating in nature which means they will donate electrons and thus favours electrophilic aromatic substitution reaction. Whereas nitro groups is strongly deactivating in nature which means they will withdraw electrons from the ring.

Question 9 1 pts Which of the following statements describes the reactivity of alkynes? An alkyne is an electron-rich molecule and therefore reacts as a nucleophile. When a symmetrical internal alkyne reacts with HBr, two products are formed. Unlike alkenes, alkynes fail to undergo electrophilic addition reactions The o bonds of alkynes are greater in energy than the rt bonds and, therefore, are more reactive Alkynes react as electrophiles, whereas alkenes react as nucleophiles What is...
