Ester formation.

In Ethanol The HIGHER concentration, the LESSER the antiseptic acitivty. ( T/F)

True.

The longer the carbon atom chain, the higher the antiseptic activity up to the 8th carbon atom (octanol) and if there is branching, this causes a decrease in antiseptic action of alcohols except for isopropyl alcohol. (T/F)

True.

The higher the MW, the higher antiseptic action but above 9 carbon chain, there is a loss in antiseptic action because it can no longer penetrate the microbial cell. (T/F)

True.
