Loveneet Saini 6 years, 3 months ago

Limiting molar conductivity is the molar conductivity of an electrolyte when concentration approaches to zero

Subho Fouzdar 6 years, 3 months ago

Limiting molar conductivity of an electrolyte is the sum of limiting ionic conductivity of cation and anion, each multiplied by number of ions present in one formula unit.

Rishabh Rathi 6 years, 3 months ago

Limiting molar conductivity is the conductivity when dilution is infinite, it means every ion is far apart such that they do not interect with each other.

Which element shows more acidic character HI OR HF,and why????

Posted by Anjum Siddiqui 6 years, 3 months ago

CBSE > Class 12 > Chemistry

3 answers

Nishu Goyal 6 years, 3 months ago

HI due to low bond dissociation enthalpy it can easily release H+ ion hence act as better acid than HF in which strong hydrogen bonding is found.

Jd Chouhan 6 years, 3 months ago

HI large size of I and down the group it incerese H is small and I is large easily accomadate... so HI has higher acidic character than compare to all...

Idoform

Yogita Ingle 6 years, 3 months ago

Ethanol is a primary alcohol whereas propan-2-ol is a secondary alcohol

And secondary alcohol gives Iodoform test whereas Primary alcohol does not give this test.

Here, is the explanation of the Iodoform test given by propan-2-ol:-

Addition of I₂(aq) (usually I₂ dissolved in KI, shown here reacting with 2-propanol
2 NaOH + I₂ + CH₃CH(OH)CH₃ → 2 NaI + CH₃COCH₃ + 2 H₂O
oxidizes the hydroxyl group to a ketone,

The ketone formed reacts with the I2(aq) in a substitution reaction to produce a triiodoketone, for example triiodoacetone.
CH₃COCH₃ + 3I₂→ CH₃COCI₃ + 3HI

F2 has lower bond dissociation enthalphy than cl2 why

Posted by Karan Dhoundiyal 6 years, 3 months ago

CBSE > Class 12 > Chemistry

2 answers

Khuskaran Sidhu 6 years, 3 months ago

Due to small size & interelectronic repulsions, bond lenth increses

Loveneet Saini 6 years, 3 months ago

Because in flourine two flourine atoms there is very small bond length due to its smaller size so two flourine atons are very close to each other and there is greater repulsion between non bonding electrons which makes the F2 bond very weak so there is lower bond dissociation enthalpy .
