1. Compounds that contain a hydroxyl functional group are known as A) aldehydes B) ketones C) alkanes D) alkenes E) alcohols Alcohols are generally represented by the formula R-OH. The –OH group is known as hydroxyl group. 2. Which organic compound is an electrolyte? A) C 2 H 6 B) CH 3 Cl C) HCOOH D) CH 3 OH E) C 6 H 12 O 6 HCOOH (formic acid) is a weak acid. In solution, it will undergo slight dissociation as follows: HCOOH H + + HCOO - The presence of ions will allow an aqueous solution of HCOOH to conduct electric current, hence, it will be an electrolyte. 3. Which of the following compounds cannot exist? A) CH 3 CH 2 CH 2 OH B) CH 2 =CHCH 3 C) CH 3 OH D) CH=C=CH E) All may exist The correct formula should be CH 2 =C=CH 2 4. Which general formula applies to hydrocarbons with one double covalent between adjacent atoms? A) C n H 2n+2 B) C n H 2n C) C n H 2n-2 D) C n H 2n-4 E) C n H 2n-6 C n H 2n is the general formula for alkenes (HC’s with double bond in the structure)
