Answer 1

Answer :-

Physical properties of reagents and products

Name	Structure and formula	Molar mass (g/mol)	Density (g/ml)	M.P. (°C)	B.P. (°C)
1) Ethyl acetoacetate	CH3 Нас	130.14 g/mol	1.021 g/ml	-45 °C	180.8 °C
2) Sucrose	CH20H CH2OH ОН Но ОН CH2OH ОН ОН	342.2965 g/mol
3) Disodium hydrogen phosphate	о Р — О- но Na -Nat Na2HPO4	141.96 g/mol (anhydrous)
4) Sodium borohydride	B Na* H H H I- NaBH4	37.83 g/mol
5) Ethyl-3- hydroxybutyrate	ОН О Hзс "CHз	132.16 g/mol			170 °C

(I HAVE LEFT BLANKS IN PLACES WHERE THERE WAS A BLACK COLOURING IN THE IMAGE OF THE QUESTION)

Structural formula :-

1) Ethyl acetoacetate : C₆H₁₀O₃

2) Sucrose : C₁₂H₂₂O₁₁

5) Ethyl-3-hydroxybutyrate :  ‎C₆H₁₂O₃

( I think instead of fourth chemical, the structural formula for  Ethyl-3-hydroxybutyrate​​​​​​​ is asked, as sodium borohydride will only have it's chemical formula (NaBH₄), which I have already provided.)

(I HAVE NOT GIVEN THE SECOND TABLE, AS I THINK IT'S FOR YOU TO ANSWER ACCORDING TO MAYBE AN EXPERIMENT THAT YOU MUST HAVE DONE, AS ALL THOSE VALUES OF VOLUME, MASS AND MOLES ARE NOT FIXED. THE FIXED VALUES ARE GIVEN IN THE FIRST TABLE.)

(Note :- If you liked the answer, then please give a thumbs up and if you have any doubts, then do ask. I hope you expected this answer only, as you did'nt mention anything in written form excluding the question image.)
