lowering boiling point

may or may not follow this general rule, as a more symmetrical molecule typically packs better, requiring more energy (higher melting point) to melt the solid

length character the shorter the bond,

C(n)H(2n+2)

hydrocarbons, bp increase with more number of carbon (molecular weight or molar mass) electronegative atoms, increase bp when compared to a molecule of similar weight with a less polar group or if hydrogen bonding is possible

combustible

base- proton acceptor acid- proton donor nucleophile- electron donor with the formation of a bond lewis base electrophile- electron acceptor lewis acid

cb is 1) charge 2) size, electronegativity 3) resonance 4) inductive

three carbons coming off of the carbons

ch3 off of the second carbon Ch3(ch3) coming off of chch3 total carbon 4 even with the coming off one

ch3 (ch3)coming off of the chch2ch3 total carbon 5 even with the coming off one

ch3( ch3)2 coming off from both sides of cch3 total carbon 5 even with the coming off ones

alkane= c-c alkeyne= c=c alkyne= c (triple bond) c

R-c (triple bond) n

R-OH

R-NH2 R-NH-R R-N-R n with three r coming off of it l R
