When 2ethyl3methyl1pentene is treated with CH3OH in H2SO4 How many different methoxy ether would be formed in significant amount

• When, ​2ethyl3methyl1pentene is treated with $C{H}_{3}OH$ in $H_{2}S{O}_4$ 2ethyl2,3dimethyl-methoxy butane is formed.
• The carbon near the oxy group and the carbon near this carbon are chiral in nature because all the 4 substituents around it are different.
• So the number of chiral centres, $n=2$
• Hence, the number of possible stereoisomers is: $2^n=2^2=4$
