I got a syntax error but I do not know what have I done wrong?

local part = game.Workspace.Part

if part.Touched:Connect(function() then
	print("Hello")
	end) 

syntax error please help me fix

if part.Touched:Connect(function() then

that's the error: you used 'if then' and ':connect()' in eachother. events work like this:

Instance.Event:connect(function(inputsIfAnyAreNeeded,input2IfNeeded)
	-- code
end)
