which these functional groups could release a proton and ameet the pH of the 12. cell? A) Amino B) Carboxyl C) Sulfhydryl D) Methyl E) Carbonyl 13. The two molecules shown in the figure above are best described as A) optical isomers. B) enantiomers. C) structural isomers. D) cis-trans isomers. E chain length isomers. NC C/ H, C/ 14. The two molecules shown in the figure above are best described as A) enantiomers. B) radioactive isotopes. C) structural isomers. D) nonisotopic isomers. E) cis-trans isomers. 15. dehydration synthesis reactions forms polymer molecules which functional groups may be involved in these reactions? A) Always carboxyl groups B) Carbonyl groups D) Maybe be carbonyl or carboxyl groups E) Maybe be hydroxyl or carboxyl groups

Explanation / Answer

12. The answer is: B. carboxyl

Carboxyl groups can release H+ into solution, making it acidic.

13. The answer is: E. chain length isomers

The two compound differ in chain length.

14. The answer is: E. cis-trans isomers

One of the compound is polar and the other is non polar.
