Conjugated dienes undergo the usual reactions of alkenes, such as catalytic hydrogenation, radical additions, and electrophilic additions more readily than most alkenes or While for 1,4-pentadiene the sp 2-hybridization leads to a bond angle of 120° between the single and double bond, in 1,4-pentadiyne it is a 180° angle due to the sp-hybrid orbital. Two stable conformations, s-trans and s-cis, were found in which s-trans is more stable. An axis of symmetry will never by itself generate an achiral compound. Compare that to the approximately 250 kJ/mol released when the two isolated double bonds in 1,4-pentadiene are hydrogenated, also forming pentane. Permanent link for this species.
