- Calculate the number of elements of unsaturation implied by the molecularformula C6H12Draw the structure of the two tertiary (3°) amines with molecular formula C6H15N that contain a group with 3 carbon atoms in the largest group. You do not have to consider stereochemistry. You do not have to explicitly draw H atoms.DHA is a fatty acid derived from fish oil and an abundant fatty acid in vertebrate brains. Hydrogenation of DHA forms docosanoic acid [CH3(CH2)20CO2H], and ozonolysis forms CH3CH2CHO, CH2(CHO)2 (five equivalents), and HCOCH2CH2CO2H. What is the structure of DHA if all double bonds have the Z configuration?
- Draw the structure of the one tertiary (3°) amine with molecular formula C5H13N that does not contain a 3-carbon chain. You do not have to consider stereochemistry. You do not have to explicitly draw H atomsWrite the structural formula of a compound with an unbranched chain of five carbon atoms that is an alkane. You do not have to consider stereochemistry. Assume for the purposes of this problem that, to be an alcohol (-ol) or an amine (-amine), the hydroxyl or amino group must be bonded to a tetrahedral (sp3 hybridized) carbon atom. If more than one structure fits the description, draw them all. Ensure alkyne bonds are drawn linearly.This is an isomer of C4H10O, and it’s not an alcohol. What could the structure be, and what are the degrees of unsaturation? Which peaks would correspond with which carbons?
