Interpretation:
The structural formulas and names of the compounds identified from a reaction sequence are to be predicted.
Concept Introduction:
Electrophiles are electron deficient species which has positive or partially positive charge. Lewis acids are electrophiles which accept electron pair.
Nucleophiles are electron rich species which has negative or partially negative charge. Lewis bases are nucleophiles which donate electron pair.
Free radical is an atom, molecule or ion that has unpaired electrons which makes it highly chemically reactive.
Substitution reaction: A reaction in which one of the hydrogen atoms of a hydrocarbon or a
Elimination reaction: A reaction in which two substituent groups are detached and a double bond is formed is called elimination reaction.
Addition reaction: It is the reaction in which unsaturated bonds are converted to saturated molecules by the addition of molecules.
Cholesterol is essential for human life. In the human body, it is produced as an intermediate in the biosynthesis of all steroids. In a molecule of cholesterol, there is no internal plane of symmetry, and hence, every carbon atom is different, and each chiral carbon has four different groups. A single unit of cholesterol consists of eight tetrahedral chirality centres.
Cholestane is a group of saturated tetracyclic triterpenes. They contain

Calculate the electronegativity difference ΔχO-C across the C=O bond and the electronegativity difference ΔχC-H to confirm or correct your predictions. For any strongly polar bond(s) on the molecule, draw the bond dipole moment adjacent to the bond in the VSEPR structure above, using crossed arrow notation to show the direction of the positive and negative bond dipoles. Predict whether the overall molecule should be polar or nonpolar. ___________________ Explain your reasoning below. If the overall molecule is polar, draw the net dipole next to the molecule, using crossed arrow notation to indicate the direction of the dipole.arrow_forward
