As the packet propagates thru the network, the destination address field will remain the same which is pc2 ip address. The destination mac address will change from each router interface untill eth0 on R2 which will assign the frame header with pc2 mac address. I assume from pc1 & sw1 the destination address will be that of R1 eth0. Someone may correct me if am wrong.

1. PC2 IP address
2. R1 eth0 MAC address.

only the mac address changes on the route.. source to destination the ip address remains the same unless your using nat... then it would be the source address on the 1st router
