Since iodide is a good leaving group, Ethyl iodide is an excellent They are often written as RO -, where R is the organic substituent. Safety Statements- The first step in the reaction is to deprotonate the alcohol using a base, in this case, potassium carbonate is used to denature the protons from the alcohol considering that the protons of the alcohol groups are not very acidic with a Pka of about 16-18 which means that it will be very difficult to get rid of them. .
