alkane formula?

alkenes formula?

alkynes formula?

Every pi bond results in?

Can give an idea of the possible structures based on the ratio of C to H?

HID is the

IHD is?

What possible arrangements arise with multiple double or triple bonds?

What arrangement is especially important for pi bonds to interact?

Type of arrangement exhibited by: C=C=C

Type of arrangement exhibited by:

C=C-C=C

Type of arrangement exhibited by:

C=C-C-C=C

Alenes are ?

What is trigonal planar bond angle?

alkenes are

What arrangement is this?

the double bond in an alkene is what? which makes it not rotate freely...

Because the double bond of cis trans isomerism of alkenes is so rigid, the substituents on the carbon atoms will

If two non-hydrogen atoms or groups are on the same side of the double bond they are?

If two non-hydrogen atoms or groups are on the opposite side of the double bond they are?

Cis and trans arrangement have different physical properties because

under the normal conditions the two isomers will not interconvert since you would have to break the what bonds?

Using light or heat it is possible to interconvert ?

What is happening in the image?

chemical reactivity of alkenes arises from the ?

is the pi bond weaker than the sigma bond where the electrons reacts first

the reagent will add across the double bond so these are called?

What reaction is this?

what are electron deficient and have an empty p orbital (sp2 hybridized)

Are all carbocations created equal? If so are there predictable patterns for which ones with form?

Carbocations have order of stability from 3 sources:

the electrons in C-C σ bonds will be pulled closer to the C+ helping to minimize the charge. Note: this does not work for C-H bonds.

this is a orbital interaction between adjacent C-H bonds that can overlap the empty p orbital of the C+, this again helps to minimize the charge on the C+

a carbocation immediately adjacent to a π system (double bond, triple bond or aromatic ring) can be stabilized by resonance. This lowers the energy by spreading the charge over more atoms, i.e.

Carbocations are susceptible to 1,2-hydride shifts, where an adjacent H atom (and its bonding electrons) shift to the C+ to produce a more stable carbocation, i.e

what is also possible for methyl groups. They are shifts that are common when a tertiary, allylic or benzylic carbocation is produced.

What is the addition of Cl2 and Br2, across a double bond to product 1,2 dihalide alkane

What is usually dissolved in chloroform or carbon tetrachloride?

what reaction is rapid at room temperatures?

Addition of ???? is a common chemical test for the presence of double bonds as the red colored ???? solution turns colorless when it reacts with an alkene

A halogenation reaction relies on the polarizability of the ?
