No need to Transcribe For each reaction, write the structural formula for the organic reagent and the major product (if one forms). If the product is wrong, partial credit is possible if you identify the type of reaction, do the reagents approach ANTI or SYN, does it follow Markinokov (or opposite or NA). 4-methy-l,4-pentadiene KMnO4 + H+(aq) - 4-methyl-1,4-pentadiene + H2 with Pt/Charcoal - 3-pentyne + Li + NH3(I), anhydrous - 1-Methyl-cyclohexene + (1) Hg(OAc)2 + AcOH, HOH, THF (2) NaBH4 1-Methyl-cyclohexene + (1) BH3, THF (2) H2O2 & OH- CH3CH +(1) NaNH2 +(2) CH3CH2I- F2C CH2 + benzoyl peroxide- Methylcyclohexene + NBS and HOH & DMSO- Rubber is a polymer of butadiene. After the polymer forms, there are still many CC double bonds in the rubber. As tires \"age\" they form \"dry rot\" alone the side NOT the surface that \"hits the road\". Ozone is the major air pollutant most often described in Lexington (and many other places). Can you explain why/HOW the ozone causes rubber to disintegrate......

Solution

1.

a. sigma bond is a end to end over laping of orbitals, normally hybrid bond. sigma bond is singal bond.

pi bond is side to side overlaping of unhybridized orbitals. pi bond along with sigma make double bond.

b. electrons of every bond are between nuclei and electrons or dipole attraction, these are strong bond or covalent bonds and weak or dipole dipole interaction.

2. in NaOCH2CH3 NaO is ionic OC is polar covalent CC is polar covalent and CH is non polar covalent.

3. completing reaction CH3CCH+NaH2==>CH3CCH2+NaNH

it is an acid/base nucleophilihc substitution reaction, where as in 1st step of acid/base rx amid ions act as base removing the acidic end H to generate acetylide ion, carbon nucliopile. and in 2nd step where carbanoin reacts with electropilic carbon in alkylhalid with loss of leaving group forming new C-C bond.
