2-Pentyne, an organic compound with the formula CH 3 CH 2 C≡CCH 3 and is an internal alkyne. It is an isomer of 1-pentyne, a terminal alkyne. 1-Pentyne. Synthesis
[c] [2] For example, a hypothetical weak acid having K a = 10 −5, the value of log K a is the exponent (−5), giving pK a = 5. For acetic acid, K a = 1.8 x 10 −5, so pK a is 4.7. A higher K a corresponds to a stronger acid (an acid that is more dissociated at equilibrium).
Constitution formula for isomers of C 5 H 8 with CAS numbers. The molecular formula C 5 H 8 may refer to any of the following hydrocarbons: . Pentynes:; 1-Pentyne; 2-Pentyne; 3-Methyl-1-butyne or isopentyne, CAS 598-23-2

In acetylene, the H–C≡C bond angles are 180°. By virtue of this bond angle, alkynes are rod-like. Correspondingly, cyclic alkynes are rare. Benzyne cannot be isolated. . The C≡C bond distance of 118 picometers (for C 2 H 2) is much shorter than the C=C distance in alkenes (132 pm, for C 2 H 4) or the C–C bond in alkanes (153 p
