For phenyl derivatives of the cyclo- pentane group see F.
For example, the difference due to an increment of CH 2 is about 56.6, as is shown in the following table: - Since the critical volume of normal pentane C5H12 is 307.2, we have H 2 = C 5 H 12 -5CH 2 =307.2 - 5 X56.6 =24.2, and C=CH2 - H2= 32.4.
65, well, 7riwv, fat), a hydrocarbon of the paraffin series, probably a pentane, C 5 H 12, discovered by K.
Similarly, pentane, C 5 H 12, and hexane, C6H14, may exist in three and five theoretically isomeric forms respectively; confirmation of this theory is supplied by the fact that all these compounds have been obtained, but no more.
When heated with fuming hydriodic acid to 300° C. it yields normal pentane and ammonia, and hydrogen peroxide oxidizes it to glutarimide and to a piperidinium oxide or oxime (R.
