Brainberene, a compound isolated from an organic chemist’s brain, has the molecular formula C16 H26. When Brainberene is subjected to catalytic hydrogenation using an excess of hydrogen, 1 mol of Brainberene absorbs 3 mol of hydrogen and produces B: C16 H32.
1) What is the element of unsatuation (IHD) of Brainberene?
2) How many double bonds and rings do Brainberene has? Laboratory experiments revealed that Brainberene has no triple bonds.
3) What is the IHD of B? d) How many double bonds and rings does B has? 12

1. An experimental technique called ¹3C-Nuclear Magnetic Resonance Spectroscopy
allows chemists to tell how many different kinds of carbon there are in a molecule
and whether carbons are primary (1°), secondary (2°), tertiary (3°), or quaternary (4°).
Give dash (Kekule) structures (i.e., use lines for electron pair bonds) for the
following compounds having a molecular formula C6H12. Also, on each
structure, identify carbons as 1º, 2º, 3º, 4º; tell how many different kinds of C's
there are; and designate which C's are equivalent.
a) A compound having only single bonds and only secondary carbons.
b) A compound having only single bonds and primary, secondary, and
tertiary carbons.
c) A compound having only single bonds and only primary, secondary, and
quaternary carbons.
d) A compound having only single bonds and primary, secondary, tertiary,
and quaternary carbons.
