HRA Taxability - Income Tax

I am a salaried employee and want to purchase a flat for my residence. From the taxation point of view, will it be advisable to purchase the same in my name or in my HUF s name. My further query is whether the HUF can charge any rent from me? If so, can I claim exemption from tax allowable under Section 10(13) on the house rent allowance being paid to me by my employer and also whether the HUF will get the standard deduction of 30% u/s 24b on the rental income received by it.
