Full worked solutions to the June 2026 End Term paper for Applied chemistry (BS104), GGSIPU first semester B.Tech. All 26 questions and parts the paper set are answered, including both alternatives wherever the paper offered a choice, so nothing depends on which questions you would have attempted. Derivations are written out in full and every numerical carries its working and its units. The questions are reproduced from the paper, so this document stands on its own; it is the answers to that paper, not the paper itself, which is listed separately.
