Question

Alkyl groups are activating substituents and ortho, para-directors. Trioxane is a cyclic trimer of formaldehyde Very strong IR C=O strech around 1710 cm^-1 for ketones Paraformaldehyde is a polymer of formaldehyde Conjugation lowers the carbonyl stretching frequencies Protons closer to the carbonyl group are more deshielded. McLafferty Rearrangement requires at least one Gamma-H to the aldehyde An alkene is formed as a product of Mclafferty rearrangement A Grignard reagent can be used to make an alcohol Grignard reagent act as an electrophile. Pyridinium chlorochromate (PCC) oxidixes primery alcohols to aldehyde Na_2Cr_2O_7/H_2SO_4 is an oxidizing reagent. Ozonolysis of alkenes gives Ketones or aldehydes Clemmensen reduction is a kway to convert acylbenzene ro alkylbenzene Witting reaction converts the cabonyl group into a new C=C double bond Acetal obtained from aldehyde and ketal obtained ketone
