Best Answer: Ethyl alcohol, at the concentrations used in most antibacterial preparations, kills bacteria by disrupting membranes and by denaturing proteins. Ethylalcohol is miscible in water (that is, completely soluble). But ethyl alcohol can also dissolve in the membranes of cells.
A one carbon alcohol is methanol (methyl alcohol), two carbons is ethanol (ethyl alcohol), three carbons is propanol. A partcicular arrangement of those three carbons gives you isopropyl alcohol or isopropanol. Ehtyl alcohol is the stuff you buy in the liquor store.eport Abuse. denatured alcohol is ethyl with added stuff to make it undrinkable. It is used as a solvent. ethyl is C2H5OH propyl and isopropyl are C3H7OH propyl and isopropyl have the same basic formula, but the molecules look different.
