Which of the following is not equal to 0.536 kilometers?
53.6 hectometers (hm)
536 meters (m)
536.000 millimeters (mm)
53,600 centimeters (cm)

53,600 centimeters

Explain; kilo=1000                          

              hecta=100

              deca=10

              unite=0(meter,leter,

              deci=0.1

              centi=0.01

              milli=0.001

0.536 kilo is opposite of 536,000 milli

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.
