Nhưng trong môi trường kiềm nó chuyển hóa thành glucozơ nên trên thực tế các phản ứng xảy ra trong môi trường kiềm như phản ứng tráng gương hay khi tác dụng với Cu(OH)₂/OH^- fructozơ vẫn tham gia phản ứng. Từ đó cũng có thể dễ dàng thấy rằng, để phân biệt glucozơ và fructozơ chúng ta có thể sử dụng các phản ứng xảy ra trong môi trường axit như nước Br₂. Khi đó glucozơ phản ứng (tính chất của nhóm chức –CHO) còn fructozơ thì không (chức xeton không tác dụng với dung dịch nước Br₂).<o:p></o:p></span></div> <div class="MsoListParagraphCxSpLast" style="mso-list: l0 level1 lfo1; text-indent: -.25in;"> <!--[if !supportLists]--><span style="font-family: "Times New Roman","serif"; font-size: 13.0pt; line-height: 115%; mso-fareast-font-family: "Times New Roman";">-<span style="font-family: 'Times New Roman'; font-size: 7pt; line-height: normal;">         </span></span><!--[endif]--><span style="font-family: "Times New Roman","serif"; font-size: 13.0pt; line-height: 115%;">Mantozơ: Do phân tử mantozơ còn nhóm –OH hemiaxetal tự do có khả năng mở vòng để tái tạo nhóm –CHO, điều này cũng lý giải khả năng tham gia phản ứng tráng gương của mantozơ.

Vân dụng chút nhé: Nhỏ vài giọt dung dịch CuSO₄ vào dung dịch NaOH dư đựng trong một ống nghiệm, thêm tiếp vào đó vài giọt dung dịch glucozơ lắc nhẹ. Trình bày hiện tượng xảy ra? Đợi cho Cu(OH)₂ tan hết, đem hơ phần trên của ống nghiệm trên ngọn lửa đèn cồn. Trình bày hiện tượng quan sát được ? Tại sao lại hơ nóng phần trên của ống nghiệm mà không phải phần dưới ? Viết phương trình minh họa.<o:p></o:p></span></div> <div class="separator" style="clear: both;"> </div> <div class="MsoNormal"> <b><span style="font-family: "Times New Roman","serif"; font-size: 13.0pt; line-height: 115%;">Đáp án: A<o:p></o:p></span></b></div>

Không chỉ là trả lời câu hỏi (1)

Câu hỏi: Các dung dịch phản ứng được với Cu(OH) 2 ở nhiệt độ thường là:      A. Glixerol, axit axetic, glucozơ                   ...
