Proteins A and B having a molecular weight of 16,500 and 35,400 move 1.3 cm and 4.6 cm, respectively, when electrophoresed through a gel. What is the molecular weight of protein C, which moves 2.8 cm in the same gel

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.
