Selelekela

Methylbenzaldehyde. Se latelang ke selelekela sa thepa, tšebeliso, mekhoa ea ho lokisa le tlhaiso-leseling ea polokeho ea methylbenzaldehyde:

 

Boleng:

- Ponahalo: Methylbenzaldehyde ke mokelikeli o se nang 'mala o monko o monate.

- Sollubility: E qhibiliha ka har'a lihlapolli tse ngata tsa tlhaho tse kang joala le ether.

- Lik'hemik'hale tsa lik'hemik'hale: Methylbenzaldehyde ke mofuta oa aldehyde o nang le mokhoa o tloaelehileng oa aldehyde, joalo ka ho itšoara ka mercaptan ho etsa mercaptan formaldehyde.
