Mechanism reaction

Give a detailed mechanism for conversion of 2,7-dimethyl-2,6-octadiene, using H3PO4, into 1,1-dimethyl-2-isopropenylcyclopentane.

Mechanism

Give a detailed mechanism for the reaction that occurs when ethyl methylmalonate CH3-CH(C=OOC2H5)2, acetone and 2-chloroacrylonitrile (CH2=CClCN) react in the presence of a base, to yield an epoxy compound CH3-C(EtOOC)2-CH2-C(NC)-O-C(CH3)2

Mechanism

Give a detailed mechanism for the reaction of o-fluorobenzophenone (Ar-C-(=O)-Ar-F)....Ar=benzene ring... with amide ion (NH2/NH3) to yield H2N-C(=O)-Ar + Ar-F

synthesis OTA#104318

For OTA 104318 This is a synthesis problem. I have four starting materials and their corresponding products. I need all the mechanisms and reagents.

stereochemistry #104318

FOR OTA 104318 I need help determining the absolute stereochemistry of three molecules and an explanation as to why it is so.

stability and (R or S) configuration OTA#104318

This is a very simple problem. I chose and explain which one of the chair conformations is more stable. Then I need assign (R or S) configuration to two molecules and determine if they are optically active.

major organic products for reactions OTA#104318

Need the major organic products of a few reactions. Stereochemistry is needed.
