at least one double bond (1 sigma, 1 pi)

alkynes have

at least one triple bond (1 sigma, 2 pi)si

sigma bond is ____ than a pi bond

stronger

but-

4

propane

c3h8

addition polymer

a polymer that forms by simple linking of monomers without the co-generation of other products

ex. Polyethylene is an addition polymer formed from ethylene (C₂H₄) monomers

condensation polymer

polymers whose process of polymerization involves a condensation reaction

ex. cellulose, starch, polypeptide chains of proteins, nylon, polyester

polymerization

any process in which relatively small molecules, called monomers, combine chemically to produce polymers

ethane

c2h6

amide bond

linkage between an amino group (-NH2) and a carbonyl group (-C=O)

Cr and Cu are exceptions to the normal filling order of electrons

Cr: [Ar] 4s1 3d5

Cu: [Ar] 4s1 3d10

alcohols

-OH

-nol

aldehyde

=O

- H

-al

ketone

- C=O -one has priority

for naming cycles, if only cycle:

(substituent)(cyclo)(meth,eth,prop,but,pent)(-one)

if the cycle is a substituent:

(#)(cyclo)(pent,hex,hept)(-yl)(pent,hex of line)(-ane)
