The question you are actually asking is: "For which connected matrix Lie groups $G$ the exponential map is surjective?" I do not think there is a comprehensive answer beyond "sometimes yes, sometimes not". It is known that for compact connected Lie groups exponential map is surjective. For some rather general partial sufficient conditions in the noncompatc case see the paper The surjectivity of the exponential map for certain Lie groups by M.Moskowitz.
