The equation for the combustion of methanol is 2CH3OH + 302 =2CO2 + 4H2O. How many liters of carbon dioxide are produced by the combustion of 64.0 g of methanol (CH3OH)? 22.4 L CO.
89.6 L CO2
11.2 L CO2
44.8 L CO.​

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.
