Hydroboration oxidation of 4-methyl-octene would give
1 4-methyl octanol
2 2-methyl decane
3 4-methyl heptanol
4 4-methy-2-octaone
Explanation:
: Hydroboration-oxidation of alkenes give alcohols containing same number of carbon atoms. The addition follow anti-Markovnikov's rule. Boron atom act as an electrophile. Main two steps are involved. Reagent used $\mathrm{BH}_3 \& \mathrm{NaOH} / \mathrm{H}_2 \mathrm{O}_2$.

Ziegler catalyst to manufacture polyethylene is made by the reaction
1 $\mathrm{TiCl}_4$ with $\mathrm{Al}\left(\mathrm{CH}_3\right)_3$
2 $\mathrm{TiCl}_3$ with $\mathrm{CH}_3 \mathrm{Cl}$
3 $\mathrm{TiCl}_4$ with $\left(\mathrm{C}_6 \mathrm{H}_5\right)_3 \mathrm{CCl}$
4 $\mathrm{TiCl}_4$ with $\mathrm{ZnCl}_2$
Explanation:
: Ziegler natta catalyst which is a combination of diethyl aluminum with titanium tetrachloride at a temperature of $333 \mathrm{k}$ to $342 \mathrm{k}$ and a pressure of $6-7 \mathrm{~atm}$. Polythene is made by the reaction of multiple ethylene molecule in the presence of catalyst (Ziegler natta) to break the double bond and connect the carbon atoms into a chain.
: A conjugated diene is a molecule that has two double bonds. It the molecule is also a hydrocarbon. It is called alkadiene. When the double bond are separated from each other by two or more single bond, they are called isolated double bonds. Isolated double bonds undergo normal alkene reactions revealing that no interaction occurs between then, the double bond are separated by single bond atypical reaction occur. Such arrangement is called conjugated double bond or conjugated diene.
