In the most stable chair conformation of trans-1,2-dichlorocyclohexane the relationship between the two chlorines is which of the following? a. Anti
b. Gauche
c. Eclipsed with a 0 degree dihedral angle
d. Eclipsed with a 120 degree dihedral angle

chemists can use the electron cloud model to assign electrons to different atomic orbitals. atomic orbitals also explain the patterns in the periodic table

explanation:

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.
