Looks to be Dracaena fragrans ‘Massangeana’. Other cultivars can look similar, but as this is the most widely available cultivar, I 'll go with with the most probable answer.
They are variegated so should have a yellow stripe, but your specimen looks like it desperately needs some more light. Word of warning - don't immediately stick it in the sunniest spot you can find as it might scorch. Move it progressively towards brighter light (indirect light from a window ideally).
It would be worth checking that it isn't sitting in water, as overwatering can lead to yellowing of leaves and is a more serious problem.
You could try adding a little general purpose houseplant fertiliser, following the manufacturer's instructions, to rule out any nutrient deficiency.
They are quite tough plants, so it should recover.
