The structure of the corresponding alkene and the reagents used for converting the given alkyne into the epoxide has to be given. Concept Introduction: Epoxides are obtained by the conversion of Alkenes using Peroxy acids and Halohydrins. Epoxides from Peroxy acids: The commonly used Peroxy acids are meta-Chloroperoxybenzoic acid (MCPBA) and Peroxyacetic acid. This process is stereospecific. If the substituent are cis to each other in the alkene, then it will remains cis to each other in Epoxide, and if the substituent are trans to each other in the alkene, then it will remains trans to each other in Epoxide. H 2 /Ni 2 B : Alkynes can be semi hydrogenated with the help of the reagent H 2 /Ni 2 B ( Nickel boride) and the syn addition of hydrogen occur.

Interpretation Introduction

Interpretation: The structure of the corresponding alkene and the reagents used for converting the given alkyne into the epoxide has to be given.

Concept Introduction:

Epoxides are obtained by the conversion of Alkenes using Peroxy acids and Halohydrins.

Epoxides from Peroxy acids:

The commonly used Peroxy acids are meta-Chloroperoxybenzoic acid (MCPBA) and Peroxyacetic acid. This process is stereospecific.

If the substituent are cis to each other in the alkene, then it will remains cis to each other in Epoxide, and if the substituent are trans to each other in the alkene, then it will remains trans to each other in Epoxide.

H2/Ni2B :

Alkynes can be semi hydrogenated with the help of the reagent H2/Ni2B( Nickel boride) and the syn addition of hydrogen occur.

1) Suppose 0.1 kg ice at 0°C (273K) is in 0.5kg water at 20°C (293K). What is the change in entropy of the ice as it melts at 0°? To produce the original "water gas" mixture, carbon (in a combustible form known as coke) is reacted with steam: 131.4 kJ + H20(g) + C(s) → CO(g) + H2(g) From this information and the equations in the previous problem, calculate the enthalpy for the combustion or carbon to form carbon dioxide. kindly show me how to solve both parts of the same long problem. Thanks

we were assigned to dilute 900ppm in to 18ppm by using only 250ml vol flask. firstly we did calc and convert 900ppm to 0.9 ppm to dilute in 1 liter. to begin the experiment we took 0,225g of kmno4 and dissolved in to 250 vol flask. then further we took 10 ml sample sol and dissolved in to 100 ml vol flask and put it in to a spectrometer and got value of 0.145A . upon further calc we got v2 as 50ml . need to find DF, % error (expval and accptVal), molarity, molality. please write the whole report. thank you The format, tables, introduction, procedure and observation, result, calculations, discussion and conclusion
