Mixed Version Support to a Data Guard Physical Standby is NOT supported.
No you cant .... Oracle versions needs to be the same.... just look up Oracle docs and you will find instructions

Dear Experts ,
my production database is 11gR1 , can its physical standby database be 11gR2 ?
That is only supported during a rolling upgrade , using Logical Standby respectively Transient Logical Standby.
Here you have a higher version on the Standby temporarily.
