Concept introduction:
Geometry of an atom is determined by the number of electron groups around it. For four electron groups, the geometry is tetrahedral. For three electrons groups, the geometry is trigonal planar, and for two electron group, it is linear.
An electron group is a lone pair or a bond. A single bond, a double bond, and a triple bond all count as just one electron group each.
Molecules in which an atom with a lone pair or a multiple bond is present next to a single bond can exhibit resonance.
The groups attached to a single bond can rotate relatively freely around the bond axis as it does not involve any change in the overlap of the bonding orbitals.
Groups attached to a double or triple bond cannot easily rotate around the bond axis as this involves a substantial reduction in overlap of bonding orbitals, equivalent to breaking of one (or two ) bonds.

- True or false 4-bromoaniline could also be named o-bromoaniline. A typical unsaturated fatty acid has a trans double bond in its structure. Trytophan is a hydrophillic, non-polar amino acid. Glucose is a substrate. The substrate for the enzyme succinate dehydrogenase is succinate. If hydrogen bonding between amino acids in the same polypeptide give a coiled shape to the protein we have an example of primary protein structure. A salt bridge would be the type of interaction between two leucines in a tertiary protein structure. Isomerases catalyze the bonding of molecules using ATP energy.arrow_forwardDetermine if 2-methylocta-4,6-dien-1-amine contains any chiral carbons. If there are chiral carbons, circle or highlight all of them. If it does not contain any chiral carbons explain why none of the carbons are chiral.arrow_forwardUsing only C, H and O, write a structural formula for the lowest-molecular-weight chiral molecule of each of the following compounds a) Alkane b)Alcohol c)Aldehyde d)Ketone e)Carboxylic Acid I realise this question has been asked but the previous seen formulas do not work for my homework.arrow_forward
- Identify the functional groups present in THC. Is the molecule likely to be hydrophilic or hydrophobic? Would you expect THC to build up in fatty tissues in the body, or would it be readily eliminated in the urine?arrow_forwardPlease mark the chiral centers and encircle the sp2 carbonsarrow_forwardLinolenic acid (Table 10.2) and stearidonic acid are omega-3 fatty acids, unsaturated fatty acids that contain the first double bond located at C3, when numbering begins at the methyl end of the chain. Predict how the melting point of stearidonic acid compares with the melting points of linolenic and stearic acids. A current avenue of research is examining the use of soybean oil enriched in stearidonic acid as a healthier alternative to vegetable oils that contain fewer degrees of unsaturation.arrow_forward
