According to “Structure of Free Molecules in the Gas Phase”, in CRC Handbook of Chemistry and Physics, 97th Edition (2016), William M. Haynes, ed., CRC Press/Taylor and Francis, Boca Raton, FL., the bond angles in propane are \$\angle\ce{CCC}=112^\circ\$ and \$\angle\ce{HCH}=107^\circ\$ Therefore, the remaining bond angles should each be about Solution for The C-C-C bond angle in propane, C3H8, is closest to A. Compare the C-C-C bond angels in propane, gauche butane, eclipsed butane, and 2,2-dimethylbutane. 109.5° C. 120° D. 180° Propane which is 3-carbon alkane also have the same bond angles. Explain the reason the bond angle in propane is not 109.5, and the reason for the increase in angle … Explain the reason the bond angle in propane is not 109.5 degree, and the reason for the increase in angle of the other structures. Compare the C-C-C bond angles in propane (Box 1), gauche butane (Box 15), eclipsed butane (Box 21) and 2, 2-dimethylbutane (Box 6). a) 90 o. b) 109.5 o. c) 120 o. d) 180 o. I know the answer, i am looking for an explanation. All bonds including the H-C-H, C-C-C, and H-C-C bonds would have a bond angle of {eq}109.5^oC {/eq}. Propane - C3H8 Carbon and hydrogen are non-metal, thus propane is formed by covalent bond. Also if you can let me know of a trick or rule of thumb I can use to figure out bond angles, that would be helpful. The C-C-C bond angle in propane, C 3 H 8, is closest to. 90° B. What is the shape of nh4?
