Question

I have an organic chemistry final coming up...help! We were given some example questions and I could really use some help with these questions (from my text)...

What are the building blocks of complex carbohydrates?

Compare the building blocks found in complex carbohydrates with those found in protiens

How are hydrocarbons similar? how are they different?

What are 3 kinds of carbon chains found in hydrocarbons?


Compare the structural formulas of butane and isobutene.

Give an example of a difference between butane and isobutane that is due to their structural formulas.

What is a substituted hydrocarbon?

What kind of substituted hydrocarbons react to form an ester?

1) the buliding unit of complex carbohydrates are monosaccharides like glucose C6H12O6.
2)the building units of protein are amino acids containing Nitrogen.
3)hydrocarbons are similar because they all have carbon and Hydrogen.They differ according to their functional group that makes its own family like Alkenes (C=C), in the family itself they differ physically but not chemically.
4)there are a lot of kinds of carbon chains not only 3 such as alkanes, alkenes, alcohols, carboxylic acid, ethers,esters, aldehydes, ketones.  these are families with diff carbon chains.
5)butane  -C-C-C-C-    Butene -C-C=C-C- or -C=C-C-C-
Butane is formed from a 4 carbon chain with Hydrogen from all sides for each C 4 bonds are needed.
while Butene is an Alkene "isn't that a diff?!"
6)THERE IS NOTHING CALLED ISOBUTANE .
7)there's nothing called subsituted hyrocarbon, some hydrocarbons react by subsitution as alkenes.
8)the hydrocarbons u r talking about are alcohols and carboxylic acids which react to form ester.
