No, that's a tertiary alcohol group in it - they ain't oxidised.

2 and 3 are wrong. sulphuric acid is not oxidised, it is a oxidising agent, it should be REDUCED
bromide ions are OXIDISED to bromine. 1- to 0.
For almost 10 years, the site XtremePapers has been trying very hard to serve its users.
However, we are now struggling to cover its operational costs due to unforeseen circumstances. If we helped you in any way, kindly contribute and be the part of this effort. No act of kindness, no matter how small, is ever wasted.
