RAP question

[1Lmania]

I'm having trouble understanding the RAP.  Can someone please tell me if any of these conveyances violate the RAP?
Thank you!



Do any of these conveyances violate the Rule Against Perpetuities? 

1)   O conveys to A for life, then to A’s children for life, then to A’s grandchildren for life. 
2)   O conveys to A for life, then to A’s widow, if any, for life, then to A’s   issue then living. 
3)   O conveys to A for life, then to A’s widow for life, then to A’s children.
4)   By will, o devises Blackacre to O’s widow for life, then to O’s children who are then alive. 
5)   O conveys Whiteacre to A for life, then to A’s first child if he survives A by 21 years.  A has no children.

You have to ask your professor if they count artificial reproductive technology first.
