Answer 1

Rt greater value = Distance Travelled by soure Distance Twiled luy soluent = sinu listonu bravelled by solwent is always than or equal to salute RF value cannot be guater than t can be equal to 1 So L Concept → More Polar the soure - Greater will be binding to Stano namy Phase [ aiuca) — howe will be Rf value & vic-versa . Polarity order Highst Rf value Lowest RH value Alkene < Aideny de < Alcohol s carboxylic and NON Polar riguese Polar Alkane will have righest Rf value , ' = 0.89 Loosley attach to aiuca (5902) = 0.57 Aldehyde More Polar than Alkene a less Polar Than Alcohol Only Dipole-Dipole interatton

Alcohol - f value = 0.24 Show Shong H-Bonding with 2002 ff Value = 0'11 Add i carboxyle Aid) Most Polay of all strongly Binds to SiOz (Stution any phase) Shong H- Bonding interaction + Stoong Dipole – Depoje interaction Lowest Rj value ( Yes We can run all these sample at same time because they have considewalle Pelawiry difference and bepraved in efficient manner
