<s> Chọn đáp án đúng với câu hỏi: Hợp chất hữu cơ X (chứa C, H, O) chỉ có một loại nhóm chức. Cho 0,15 mol X phản ứng vừa đủ với 180 gam dung dịch NaOH, thu được dung dịch Y. Làm bay hơi Y, chỉ thu được 164,7 gam hơi nước và 44,4 gam hỗn hợp chất rắn khan Z. Đốt cháy hoàn toàn Z, thu được 23,85 gam N a 2 C O 3 ; 56,1 gam C O 2 và 14,85 gam H 2 O. Mặt khác, Z phản ứng với dung dịch H 2 S O 4 loãng (dư), thu được hai axit cacboxylic đơn chức và hợp chất T (chứa C, H, O và M T < 126 ). Số nguyên tử H trong phân tử T bằng

<s> Chọn đáp án đúng với câu hỏi: Hỗn hợp X gồm hai este đơn chức, mạch hở, là đồng phân cấu tạo của nhau. Thủy phân hoàn toàn m gam X bằng dung dịch NaOH rồi cô cạn, được 40,2 gam chất rắn Y và a gam một ancol Z. Nung Y với CaO cho đến khi phản ứng kết thúc, thu được 8,4 gam một chất khí. Oxi hóa a gam Z thu được hỗn hợp T gồm axit cacboxylic, andehit, ancol dư và nước. Cho T tác dụng hết với Na dư, thu được 4,48 lít H 2 (đktc). Cho T vào dung dịch KHCO 3 dư, thoát ra 2,24 lít CO 2 (đktc). Cho T phản ứng tráng bạc hoàn toàn, tạo ra 86,4 gam Ag. Giá trị của m là
