Physical and chemical properties of geometric isomers are generally different. The general formula of alkyne is CnH2n-2. a. n-pentane and 1-pentene b. It is sp three hybridized because of all single bonds and its shape will be tetra hydro. These compounds are composed of a triple bond per molecule. Geometric isomers are isomers in which the order of atom bonding is the same but the arrangement of atoms in space is different. 2-Butyne is the most stable butyne isomer. The third carbon does not count as another isomer because if we start counting from the other end the triple bond is actually located at the second carbon. Occupational workers should be very careful during handling/using 1-butyne cylinders, The chemical formula is C 4 H 8. The reaction, RC CR H 2 Lindlar's catalyst gives the main product as.
