    • ‘Among the 4800 constituents of tobacco smoke, researchers have identified more than 100 alkanes, 150 alkenes and 55 alicyclic hydrocarbons.’
    • ‘The alicyclic compounds have one or more rings.’
    • ‘An alicyclic compound is an organic compound that is both aliphatic and cyclic.’
    • ‘Its solubility is very high in polar organic solvents as well as in benzene but it is only sparingly soluble in aliphatic or alicyclic organic solvents like hexane and cyclohexane.’

noun

Chemistry

    • ‘Further chapters describe useful methods for the synthesis of alicyclics by ring contraction, ring enlargement and transannular cyclization.’
    • ‘The characteristic that distinguishes benzene from the aliphatics and alicyclics, and that defines the aromatics, is the arrangement of electrons in the ring.’
    • ‘They are immiscible with many organic solvents, particularly linear hydrocarbons and alicyclics like cyclopentane.’
    • ‘The further separation yielded 12 fractions containing aliphatic and alicyclic, 24 containing aromatic and 1 containing nitrogen, sulphur and oxygen containing compounds (NSO fraction).’
    • ‘In discussing the alkanes as a functional group, the terms aliphatic (for the acyclic alkane substituent) and alicyclic (for the cyclic alkane substituent) are used.’
