As it has a double bonded oxygen there is equal chances of attack from ch3oh Hence you get two products i.e. Above and below position of och3

sir but why in och3 there is one och3 in axial position at alpha side and why there is two och3 at equatorial position at beta position

this maybe because of multistage reaction which is favoured by steric availability

what do you mean by multistage reaction? Iam unable to understand
