Question

I think it is Heptane-4-one.. but I am uncertain.

If you answer please make sure it is a complete answer regarding both parts

I will give a good review! Thanks

Preliminary Identification You have been given an unknown compound. In the first part of this lab, you will examine the physical properties, solubility, and elemental analysis of the unknown. Fill out the information below as best as possible 1. Physical properties a. Solid or liquid: Liquid b. Color: Colorless 2. Ignition test a. Flammability: Flammable b. Manner of melting: c. Odor of gases: Banana-like fruity odor 3. Beilstein test test for halogens): No green flame 4. Melting point: 5. Boiling point - 145 C 6. Solubility test: H2O 5% or 10% of HCI 5% or 10% of NaOH 5% or 10% of NaHCO3 Reactivity with H2504 Insoluble Insoluble Insoluble Insoluble (+) reaction 7. Elemental Analysis: Nitrogen Chlorine Bromine 2,4-DNPH Negative Negative Negative Positive 8. Prediction of functional group present and reasoning why

Answer 1

nown - - My analysis towards the Unknown sample .. :) solubility test . It is an organic compound . having no acidic or alkaline functional group, its -600H, OH, NHL are absint. . ü) 2,4-DNPH: → positive → So, carbonyl fume bional group present, ( Jezo ork-H N9 N9 Present) As + OYN R1 R O NO B ov ü) Tollen's test negetine chromic and I negeline (Red dye) so aldehyde absent No oxidisable group Presente Kelo methyl group i Iodoform test → negetine absent,

-One Boiling point of the sample = 145°c and literahore value of boiling point of Heptane - 4 - One is 193e. So, it may be sa Now, Derivative -1 » Semi carta zone of Heptane - 4-one boiling point match Derivaline -2 2,4 - Dinitrophenyl hy hasone of heptane - 4- one. boiling point matched. So, Name of the Unknown Compound's Heptane - 9-one 03 Struefrore
