I see... I thought 1 mark for the 1st dia and 2 marks for 2nd dia and so total 3 marks... *Phew* tyErm, as I have explained. The 1st diagram is the incomplete answer. Students who produced the 1st diagram will only get 1 mark.
Students who produced the 2nd diagram gets 2 marks.
Are both question same?T reacting with an excess of Na
NaO2CCH(ONa)CH2CO2Na ----> Over here Na, replaces the H in the alcohol group.
U reacting with an excess of Na2CO3
NaO2CCH(OH)CH(OH)CO2Na ---> Over here it doesn't. :s Why?
T reacting with an excess of Na
NaO2CCH(ONa)CH2CO2Na ----> Over here Na, replaces the H in the alcohol group.
U reacting with an excess of Na2CO3
NaO2CCH(OH)CH(OH)CO2Na ---> Over here it doesn't. :s Why?
Mr of S = 1 + 32 + 12 + 12 +1 + 12 + 1 + 12 + 32 + 1 = 116T reacting with an excess of Na

Same way T = 134 And U = 150
Reaction with oxygen :Can someone please give me a list of all the flames we need to know? I cant find the appropriate ones anywhere! Please thanks guyss
