can someone help

Draw a structure for the compound, C4H6Cl2, that fits the following 1H NMR data: - 2.18(3H, singlet) - 4.16(2H, doublet, J=7Hz) - 5.71(1H, triplet, J=7Hz) - You do not have to consider stereochemistry. - You do not have to explicitly draw H atoms. - In cases where there is more than one answer, just draw one
