Document Summary
Lecture 13: cycloalkanes and is connected to 2 hydrogens. Cyclic hydrocarbon: c ring structures with 3 to 30 carbons. Cyclopropane (c 3 h 6 ): drawn as triangle, each vertice represents a carbon. Cyclobutane: drawn as square, 4 carbons and 8 hydrogens. When there is 1 substituent on a ring, no numbering. Consists of a pentagon with a line from one of the vertices leading to a point away from the pentagon that represents a carbon, and two lines going from that point outwards to represent the other 2 carbons. For 2 substituents on the ring: if substituent numbers are the same, the 1st named group gets the lower number. Consider a hexagon, with a cross drawn ou from one of the vertices on the left of the hexagon and a line drawn out from the vertice on the right.
