Hi,
Both are good colleges in Delhi university but i would prefer hansraj college first for pursuing bsc in chemistry as it is one of the best colleges in delhi university and it provides excellent teaching facilities and the infrastructure is excellent and most of the things are newly built . Talking about placements,  there are very less companies that visit the college campus and that's why the placements remain low but it is definately a better choice than svc college and you can pursue for higher studies after doing graduation.
Hope it helps..
