Respuesta :

Mevalonate exists in equilibrium with compound x in aqueous solution.  the structure of compound x is a six membered ring.

The six membered is thermodynamically more stable so, the compound formed is six membered ring is more favorable. the both the  four membered and the peroxide are the high energy species. so, these are not able to form stable molecule as mevalonate. mevalonic acid is the organic compound discussed in the biochemistry. mevalonic acid contains the -CO₂H and -OH groups.

Thus , for the mevalonate exits is in the equilibrium compound x and the compound x is called the six membered ring.
