Chem 106 Exam 4 || ANSWERED CORRECTRY
Type or compounds in organic chemistry - Correct Answer carbon



Hybridization states - Correct Answer sp3=tetrahedral=109.5

sp2=trigonal planar=120

sp=linear=180



4 hydrocarbons - Correct Answer alkanes

alkenes

alkynes

aromatic hydrocarbons



alkanes - Correct Answer only single bonds

saturated (as many H as possible)

the only van der Waals force=London dispersion force

boiling point increases with length of chain

sp3- only sigma bonds-free rotation about c-c bonds

unreactive, nonpolar



isomers - Correct Answer same molecular formula, but different bonding order



cycloalkanes - Correct Answer rings

5, 6 membered rings = most stable (smaller than that, get strained and break easily)



alkenes - Correct Answer at least one c=c double bond

unsaturated

sp2-not free rotation around double bond

, addition reaction: 2 atoms add across the double bond (1 pi-bond and 1 sigma-bond are replaced by 2
sigma-bonds)



alkynes - Correct Answer at least one c-c triple bond

unsaturated

sp-linear around triple bond



aromatic hydrocarbons - Correct Answer cyclic hydrocarbons

p-orbital on each atom (planar molecule)

resonance- pi-electrons are delocalized, which stabilizes it

-undergo substitution rather than addition (H replaced by substituent)

reactions often require a catalyst



substituents on benzene ring - Correct Answer ortho=on adjacent carbons

meta=with one carbon between them

para=on opposite sides of ring



functional group - Correct Answer where reactions tend to occur



Alcohols - Correct Answer one or more --OH

much more acidic than hydrocarbons



Ethers - Correct Answer --O--

unreactive

polar



Aldehydes - Correct Answer at least 1 H is attached to the C=O



Ketones - Correct Answer 2 C's bonded to C=O
