A cyclopropyl group is a chemical structure derived from cyclopropane; it is typically produced in a cyclopropanation reaction. The group has an empirical formula of C 3 H 5 and chemical bonds from each of the three carbons to both of the other two.
A cycloalkyl group is derived from a cycloalkane by removal of a hydrogen atom from a ring and has the general formula −C n H 2n−1. [2] Typically an alkyl is a part of a larger molecule. In structural formulae, the symbol R is used to designate a generic (unspecified) alkyl group. The smallest alkyl group is methyl, with the formula −CH 3 ...
From left to right: the two isomeric groups propyl and 1-methylethyl (iPr or isopropyl), and the non-isomeric cyclopropyl group. In organic chemistry, a propyl group is a three-carbon alkyl substituent with chemical formula −CH 2 CH 2 CH 3 for the linear form.
For example, (CH 3) 2 CHCH 2 CH 3 (isopentane) is named 2-methylbutane, not 3-methylbutane. If there are multiple side-branches of the same size alkyl group, their positions are separated by commas and the group prefixed with multiplier prefixes depending on the number of branches. For example, C(CH 3) 4 (neopentane) is named 2,2 ...
Most cyclopropanes are not prepared from the parent cyclopropane, which is somewhat inert. Cyclopropyl groups are often prepared by cyclization of 1,3-difunctional alkanes. An example of the former, cyclopropyl cyanide is prepared by the reaction of 4-chlorobutyronitrile with a strong base. [1]
Alkyl groups are saturated hydrocarbons substituents with the general formula C n H 2n+1 Pages in category "Alkyl groups" The following 7 pages are in this category ...
Cyclopropane is the smallest alicyclic compound.. In organic chemistry, an alicyclic compound contains one or more all-carbon rings which may be either saturated or unsaturated, but do not have aromatic character. [1]
Alkyl compounds are chemical compounds formally derived from alkanes by replacement of one hydrogen atom with other atoms or functional groups. Alkyl compounds contain alkyl groups , C n H 2 n +1 , and have the general formula C n H 2 n +1 X, where X is any chemical element or group.
