…or I) are classified as primary, secondary, or tertiary according to the degree of substitution at the carbon to which the halogen is attached. In a primary alkyl halide, the carbon that bears the halogen is directly bonded to one other carbon, in a secondary alkyl halide to two, and…...

Secondary nitroalkanes under these conditions give tars, and tertiary nitroalkanes do not react. Addition of the sodium salt of the aci form of a primary or secondary nitroalkane to excess dilute sulphuric acid gives an aldehyde or ketone respectively. ...
alkyl halides, the use of secondary and tertiary alkyl halides often leads to low yields. Besides, the unpleasant odor of mercaptans may also limits its practical applications. An alternative method to forge C(sp3)–S bond is the reaction of alkyl halides with disulfide reagents under Barbier ...
An Extremely Mild Method for the Conversion of a Primary Alkyl Halide into a Primary Alcoholsubstitution reactionsAn extremely mild method for the conversion of RCH2X (X = Br, I) into RCH2OH is described. The method is particularly useful when R contains a base-sensitive group.doi:10.1080/...
