CHEM 110 EXAM 2 Study Guide Penn State isomers rapidly increases with the number of carbons in the formula.: https://farm3.staticflickr.com/2829/10518126314_12964714 41_m.jpg NOTE:: All carbon atoms in alkanes have four electron domains (four bonds) and are tetrahedral, with bond angles very close to the ideal tetrahedral angle of 109.5o. All carbons are sp3 hybridized and all C-C bonds are formed by overlap of sp3 hybrids on adjacent carbons, while all C-H bonds are formed by overlapping sp3 hybrids on carbon with the 1s orbital on hydrogen. The C-C bond lengths are about 154 pm, and the C-H bond lengths are about 110 pm. isobutane (branched chain): C410 Isopentane (branched chain): C5H12 Neopentane (branched chain): C5H12 Isohexane (branched chain): C6H14 Methylpentane (branched chain):

Thus they are called COMPLETELY SATURATED. Other classes of hydrocarbons can have fewer hydrogens per carbon and are formally UNSATURATED. All single bonds
