Structure of phenyl acetic acid (C8H8O2) is attached below.
No, 2-pentanone would not give a positive reaction to the Iodoform test. The Iodoform test is specific for methyl ketones (ketones with a methyl group adjacent to the carbonyl), and 2-pentanone does not have this structure. Instead, it has a butyl group adjacent to the carbonyl, which does not lead to the formation of iodoform.
Hi, Iodoform test is used for the detection of methyl ketones as methyl ketones give positive iodoform test. In this test, methyl ketone is treated with iodine (I2) in the presence of base such as sodium hydroxide (NaOH) to give iodoform(CHI3 - a light yellow coloured ppt). Chemistry of iodoform test is: Secondary alcohols also give positive iodoform test because during the reaction conditions, it gets oxidized to a methyl ketone.
The unknown carbonyl compound is likely a methyl ketone. When reacted with chromic acid, it undergoes oxidation to form a carboxylic acid. In the iodoform test, it forms a yellow precipitate of iodoform (CHI3) due to the presence of a methyl group adjacent to the carbonyl carbon.
No, methanol will not give a positive result in the iodoform test. The iodoform test is specifically used to detect the presence of compounds with the CH3CO- group in them, such as methyl ketones, which are required for a positive reaction.
The lattice energy of a compound is always negative.
Ionic compounds are neutral because, even though they consist of positive and negative ions, the relative proportions between those ions are such that the total number of negative charges is the same as the total number of positive charges, thus summing to zero.
Yes, vanillin can give a positive iodoform test. The iodoform test is used to detect the presence of a methyl ketone group attached to a carbon atom adjacent to two other carbon atoms, and vanillin has a structure that can undergo this reaction.
The compound gauge is an instrument to measure pressures, positive or negative.
Yes
Ethanol is the only primary alcohol to give the iodoform test due to the presene of methyl group attached to alpha carbon atom.
When the positive ion of a base combines with the negative ion of an acid, they form a salt compound. The positive ion from the base combines with the negative ion from the acid through an ionic bond to create a neutral compound known as a salt.
Positive ions (cations) and negative ions (anions) form an ionic compound through electrostatic attraction. The cations and anions are held together in a crystal lattice structure, resulting in a stable compound.
