Draw an Alkane with the molecular formula C4H8 as well as a possible functional group isomer and state a chemical test you can use to differentiate between the two.

Many organic molecules follow specific formulas to help identify them. For Alkanes this is: CnH2n+2 (n being the total number of carbon atoms). However, this is not the case with the...

Explain why the product of nucleophilic addition of a cyanide ion to the ketone CH3COCH2CH3 shows no optical activity

The ketone group is planar and the cyanide ion has equal chance of attacking above or below the plane. Therefore a racemic mixture of the product is formed and the product shows no optical activity

Describe the products of the following Friedl-Crafts substitution and explain the role of the AlCl3 in the reaction: C6H6 + CH3C(O)Cl + AlCl3 = ?

C6H6 + CH3C(O)Cl = C6H5C(O)CH3 + HCl

This is an example of an electrophilic aromatic substitution reaction, with the product being a ketone. The AlCl3 serves as a catalyst, converting the acyl chlo...
